Energy Observer, the world’s first hydrogen ship, is set to make a six-year journey around the world to promote renewable sources of energy. The ship will be powered by electricity generated by the sun and wind, which will be used to convert sea water into hydrogen which can be stored on board.

Sandia National Laboratories researchers say that it is feasible to build and operate a high-speed passenger ferry solely powered by hydrogen fuel cells.

After 16 months of development, Boeing has delivered a fuel cell energy storage system to the U.S. Navy for testing. The cell is being tested to determine its ability to support the energy needs of military and commercial customers.

(Image Credit: Red and White Fleet) Sandia National Laboratories and San Francisco's Red and White Fleet are partnering to to design, build and operate a high-speed hydrogen fuel cell passenger ferry and hydrogen refueling station. Hydrogen fuel cells have several advantages over the diesel engines that power most passenger ferries — no harmful exhaust emissions, higher energy efficiency, quiet operation and no risk of fuel spills. Replacing diesel engines and generators with hydrogen fuel cells could greatly improve air and water quality in harbor areas. The hydrogen refueling station is planned to be the largest in the world and serve fuel cell electric cars, buses and fleet vehicles in addition to the ferry and other maritime vehicles. The U.S. Department of Transportation’s Maritime Administration (MARAD) is funding a feasibility study to examine the technical, regulatory and economic aspects of the project. “The Maritime Administration is committed to finding new and efficient technologies for use in the maritime industry that reduce pollution and protect our environment,” said Maritime Administrator Paul ‘Chip’ Jaenichen. “This industry continues moving forward on renewable energy and clean-fuel options, and this project encourages a shift toward lower impact maritime fuels that may further green the waterborne link in our ...

ISO 8217 places a 2mg/kg limit on H2S as a safety net for crew The question of the potential hazards posed by hydrogen sulphide has been raised before in connection with the new ISO standard for marine fuels and a recent study has rekindled debate.A DNV Petroleum Services (DNVPS) field study on hydrogen sulphide (H2S) measurements in marine fuel has raised concerns about the reliability of ISO 8217:2010, which places a 2mg/kg limit on H2S as a safety net for ship personnel. In recent years ISO 8217 has undergone four revisions.The inaugural standard was agreed in 1987, while the current one was launched last July, but concerns continue to be raised about the H2S limit included in the latest revision of the standard.

Use of deficient and different versions of MSDSs A chemical tanker was instructed to load 2000 tonnes of crude sulphate turpentine (CST), a Category X cargo under MARPOL Annex II. The cargo was to be discharged to another tanker via a ship-to-ship (StS) transfer at a receiving terminal. Although there were several experienced crewmembers on board, none of them had any previous experience of this cargo, or knew about its associated hazards.The ship's Safety Management System (SMS), Procedures and Arrangements (P&A) Manual, cargo checklists and procedures were all followed, despite there being no information on this specific cargo.Prior to arrival, a briefing was conducted by the chief officer. The material safety data sheets (MSDS), were not available at the time. Accordingly, the hazards of the cargo (toxicity of H2S, organo-sulphides and mercaptans) were not properly discussed. On arrival, the shipper handed the vessel a cargo-specific MSDS. The ship's manager also supplied a generic MSDS which did not mention H2S. Because of the delayed and incomplete information from a large number of sources, the crew remained largely ignorant of the dangers of the cargo.The receiving STS ship, the terminal staff and even the cargo surveyor, who also obtained a generic MSDS ...

Guidance on the hazards associated with hydrogen sulphide Personnel working in the oil tanker industry are generally familiar with the hazards associated with the presence of hydrogen sulphide (H2S) in hydrocarbon products carried as cargo.However, the possibility that marine bunkers may also produce H2S gas is not always recognised so widely.The West of England P&I Club has issued a bulletin providing Guidance on the hazards associated with hydrogen sulphide gas evolvgd from marine bunkers.You may access the prevention bulletin hereSource: West of England P&I
